UNITED STATES JAMES E. MCGLELLAN, OF LOS ANGELES, CALIFORNIA.

CHASE Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed December 16, 1907. Serial No. 406,805.

To all whom it may concern:

Be it known that I, J AMES E. MoCLELLAN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Chase, of which the following is a specification.

This invention relates to a chase designed chiefly for use with duplicating machines and job printing, being especially adapted for use where the type is set up in the chase instead of in a composing stick, and the main object of the inventionis to obviate the use of furniture and quoins and provide simple and effective means for looking a form of any size within the capacity of the chase.

The accompanying drawings illustrate the invention, and referring thereto :Figure 1 is a plan view of the chase, the form of type being indicated by dotted lines. Fig. 2 is a section on line 20 00 of Fig. l.

The chase comprises side bars 1 and end bars 2 united therewith in any desired manner, as for example, by the dovetail construction 3, as shown. The side bars 1 are provided along their entire inner faces with square notches 4.

5 designates a cross bar which at each end is formed with a tongue 6, and the tongues 6 are adapted to fit in any of the notches 4 so that the cross bar may readily be placed at any desired position in the chase and when in position is positively held in such osition. The bar 5 is solid and preferably ma e of the same thickness as the frame and of suflicient width to permit of the tongues 6 being placed substantially at the middle thereof so that the bar can be reversed or inverted without weakening it, as would be the case if the tongues were placed nearer one edge than the other, thereby making a very convenient construction. By forming square shoulders between the notches 4, pressure can be applied in either direction at any point along the sides of the frame, thereby permitting of the type being secured at, or adjacent to, either end as well as intermediate the ends of the frame, and, if desired, two or more blocks of type can be held in position at the same time, either by using both edges of the bar 5, or by using two bars.

7 designates a locking device which comprises two bars 8 and 9, the bar 8 having a tongue 10 at one corner of each end which tongues are also adapted to engage in any of the notches 4 to positively hold the bar 8 in the desired position. The bar 9 has no tongues on its ends but is free to be adjusted laterally with respect to the bar 8 by means of a pair of right and left screws 11, which. are threaded in both bars 8 and 9 and at the center, each screw has a hexagon 12'to enable it 2 be turned by a wrench 13 as indicated in The type, indicated by dotted lines 14, is set up in the chase, either against the cross bar 5 or bar 9. The leads separating the lines of type are indicated by 15. After the type is set, the locking device is moved up so that bar 9 is close to the type and the tongues of bar 8 are fitted into the nearest notches. Then by turning the screws 11 by means of the wrench 13 the bar 9 is forced against the form and the type securely locked. By securing the ends of each screw in both bars a unitary or inseparable pressure applying device is formed which prevents the possibility of any of its parts being lost or misplaced when the device is to be applied, and by making the bars solid and of the same thick ness as the frame they can be inverted, or turned end for end, without, however turning them edge for edge and thus a very convenient structure is formed which can be quickly and very efiiciently applied at all times, and will possess the greatest strength for a given width of bar.

It will be seen that by the employment of the notches 4, the cross bar 5 and clamping device 7 may be instantly set to fit any size form.

What I claim is In a printers chase, a frame, the opposite sides of which are provided with square shoulders and notches, a solid invertible and reversible bar substantially as thick as the frame and having a tongue at each end substantially at the middle of its width and adapted to engage with said shoulders, and pressure applying means comprising two ars, each of which is substantially as thick as the frame and provided with screw threaded perforations, and one of them has smooth ends and is adapted to move freely within the frame and the other one has a tongue at the rear corner of each end adapted to engage with said shoulders, and a pair of right and my hand at Los Ange-ies,""Ca1ifornia, this 7th left screws in said perforations for permanently holding the bars together and adj ustim them relatively to each other, the centra portion of each screw being angular in cross section.

In testimony whereof, I have hereunto set day of December 1907.
